Inputting Node Properties

Properties tab (RHS) #

Used to display properties of the selected node. Select any nodes in the workspace and go to Properties Tab (RHS) to put in the node properties

New Node Properties #

Can be found at the Properties Tab (RHS) when clicking the Node button without selecting any nodes in the workspace. The properties can be configured prior to adding or importing node. Any nodes added afterwards will automatically follow the configured settings.

Spread Input #

Used to display information of all entities for better clarity. Node properties can be modified in the Spread Input tab

Properties of Node #

Mark #

The default mark will be the sequence number, such as 1,2,3… The node prefix can be customized by referring to the guide here

Location #

Represent the X, Y coordinates of the node on the Input Screen.

Ground Level #

Refers to the ground level of the node. Will either be based on the survey data imported or the platform level designed in which the node is placed on the Input Screen.

Users have the option to User Defined the level or let the software auto-detect the ground level for each of the nodes.

Water Demand #

Manual Input #

You can assign water demand to a node by entering the value manually in the Spread Input table or in the Properties tab (RHS). For manual input, ensure that the water demand value is entered with a negative sign.

Calculated Input #

 You can use the Water Demand Calculator to let the program calculate the total water demand. Follow the steps below: 

You can use the Water Demand Calculator to let the program calculate the total water demand. Follow the steps below: 

1. Select the node
2. Click Water Demand Calculator or in the Spread Input
3. Select the Building Type.
4. Enter the number of units and press “Enter’ to commit the water demand value.

 Level #

Insert Tank Water Level if the node has Elevated Water Tank. The Tank Water Level will affect the Highest Supply Level (HSL). Refer to the calculation here

Tapping Settings #

Refers to the tapping point/ reservoir where water is drawn for distribution to the network. To insert the pressure head;

1. Select the node that serves as tapping point/ reservoir
2. Toggle the Fix Head to “Yes” (either in Spread Input or Properties tab (RHS))
3. Insert the Node Head value.
4. If necessary, insert the Additional Node head value. Refer here for more information.

Hydrant Settings #

Refers to the hydrant point. To set the node as hydrant:

1. Select the node that has hydrant point
2. Toggle the hydrant to “Yes”
3. The hydrant demand will follow the hydrant flow column. No need to insert again the water demand (unless there are different demand at the node)

Flow Factors #

These coefficients will be used in the peak flow and fire flow calculation. Refer here for calculation

Rotation #

Used to rotate the node in degrees in the Key Plan and 3D View. It can be set to be iterated by software or manually input by users.

Fitting/ Appurtenance #

Used to define the type of fittings/ appurtenances and the nominal diameter used for the pipe connection.

Custom Loss #

Used to insert additional head loss. Refer here for calculation details.
